What is solar vapor absorption chiller
Vapour Absorption Refrigeration Systems (VARS) belong to the class of vapour cycles similar to vapour compression refrigeration systems.
However, unlike vapour compression refrigeration they differ in :
1) Mode of energy input.
How to find this design parameters ?
Any thermodynamic closed cycle problem is solved by mass and energy balance at different points.
Using saturation pressure/temperature tables.
Using pressure-temp-conc diagram for libr-water sol.
Using enthalpy-temp-conc diagram for libr-water sol.
Computer modeling of a single stage libr/water absorption refrigeration unit
Previously shown method is very tedious and time consuming.
A mathematical model supported by computer programming is very useful.
Empirical equations are formed using energy balance equation and charts described.
Computer model is prepared using this Empirical equations.
